PLOW.

To all ttl/omit may con-cem:

Be it known that I, ARTHUR E. BosT, a citizen ot the United States,residing at Waelder. in the county of Gonzales and State of Texas, havevinvented new and useful Improvements in Plows, of which the followingis a specification. e

This invention relates to that class of plows in which the foot istiltably supported so as to enable' the earth engaging blade to bepresented at various angles with respect to the'surface of the ground.

The main object of the present invention isto provide a simple andimproved construction whereby when the plow foot is tilted it will atthe same time be moved upward or downward according tothe direction inwhich it is tilted so as to preserve the point of the earth engagingimplement at the same level.

A further object of the invention is to produce a plow having a heelplate or runner and a tiltable foot on which the earth engaging blade ismounted, the construction Abeing such that the point of the blade willlremain substantially in the same plane as the lower edge of the heelplate or runner at all adjustments of the tilting foot carrying the saidearth4 engaging blade.

lVith these and other ends in -view which willv readily appear as thenature of the 1nvention is better understood, the same consists in theimproved constructionand novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings, Figure 1 is a side elevation of a plowconstructed in accordance with the inventioniwith dotted linesindicating a different position of the tilting'it'oot.' Fig. 2 is a topplan view. Fig. 3 is a sectional view taken through the tilting foot onthe line 3 3 in Fig. 1. Fig. 4t is a sectional detail view taken on theline 1 -11sin Fig. 1. Fig. 5 is a sectional detail view taken on theline 5&5 in Fig. 1.

Corresponding parts in the several figures are denoted by likecharacters of reference. The'invention in the present instance has beenshown appliedV to a metallic plow beam 7 having a downturned standard 8having at its lower end a flattened foot portion 9'on which the heel'plate or runner 10 is secured by fastening means, heel plate orrunnerhaving at its front end an upwardly extending nose piecei 12.

cured adjacent to the opposite sides or faces of the standard bymeans ofa bolt 13 eX- tendmg therethrough just above thefoot piece 9 are anglebraces 14 the rear ends of which serve for the attachment of'the lowerends of the handles 15. The forward ends the upper end of the nose piece12 by means of a bolt 16 extending transversely therethrough.

The plow foot -F is composed of two spaced bars 17 vhaving slots 18whereby said bars are mounted upon the bolt 16 so as to be capable of asliding movement on said bolt, it being noticed that the Abars 17 arespaced apart by the upper end of the nose piece 12, each of said barsbeing positioned intermediate the nose piece and the forward end of oneof the angle brac'es 14.. Thebolt 16 may be provided with a jam nut orIlock nut 19, and in assembling the parts care is taken to avoidtightening the nut tosuchl an extent as to interfere with the reasonablefree sliding movement of the plow. foot with respect to the bolt 16which extends through the slots in the spaced bars of the plow toot.VSaid spaced bars arejalso'conbolts 2O having'spaeare positioned adjacentto opposite sides of the standard 8 which is loosely"engaged thereby. e

The plow beam supports a plate 22 having an arcuate notched edge forminga segment rack 23. l Fulcrumed on the plate 22 concentrically with therack 23 is a V-shaped lever onbell crank L, the long arm of which 24constitutes a handle, said handle being connected with the shortarm 25by means of a. brace 26. The nlever arm 25'and the brace 26 arepositioned adjacent to opposite sides of the upper end of the plow footwith which said arm and brace are connected pivotally by means of a.bolt 27 which may be provided with a spacing sleeve 28. The long armwhich forms the handle of the lever is'provided with a suitable springactuated stop member 29 engaging the rack 23 forthe purpose .ofretaining the lever and related parts securely at various adjustments.

The plow handles 15, the lower ends of which are secured upon the anglebraces 14, are connected together near their upper ends Said handles arealso connected with the plow beam by means of pivot member or 'of theangle braces 14 are connected with y lll) braces 3l that are securelyconnected with the beam by means of a bolt 32 passing transverselytherethrough a short distance in advance of the plate 22 whichconstitutes the lever stand. A ground engaging blade 33 of any suitabletype may be secured on the plow foot-at the lower end of the latter bymeans of a bolt 34. f

From the foregoing' description, taken in connect-ion with the drawingshereto annexed, the operation and advantages of the improved plowwill bereadily understood. The heel plate or runner, as is well known, is usedfor the purpose of maintaining the plow at an even depth. In order to dothis successfully, it is obviously necessary that the said heel plateshould run in the bottom of the furrow,and it must, therefore, bemaintained in substantially the same relation to thepoint of the earthengaging blade in any position to which said blade may be tilted.Various characters and conditions of soil make it necessary tofrequently tilt the blade so as to change the angle thereof with respectto the surface of the ground, b ut such tilting, if the plow foot besimply rocked about a stationary axis, would result in raising orlowering the point of the blade with respect to the lower edge of 4theheel plate. By. the present construction7 when the lever L is rocked totilt the plow foot,

said plow foot will at the same time be slid or moved upwardly ordownwardly, according to the direction in which the lever is tilted. Thepart-s of the plow' structure are so arranged and proportioned that whenthe upper end of the plow foot isrocked in a forward direction, thustending to swing the lower blade carrying end downwardly and rearwardly,the plow foot will at the same time be slid or moved upwardly to anextentsulioient to compensate for the downward movement of the lower endthereof, thus causing the point of the earth engaging ,blade to bemaintained substantially at the same level, as will be clearly seen byreference to Fig. l of the drawings. It is evident that when the upperend of the plow foot is rocked' in a rearward direction, the plow footwill at the same time be slid or .moved downwardly a suticient distanceto obtain the desired result. The adjustment nose piece which ispositioned therebetween, l

a plow foot comprising spaced bars having slots engaging the bolt thatconnects the angle braces with-the nose piece, a suitably supportedlever having an arm connected with the upper end -of the plow foot, andmeans for securing the lever at various ad- -justments; the parts beingarranged and proportioned to maintain the lower end of 'the plow foot insubstantially the saine horizontal plane at various adjustments of theplow foot.

2. A plow beam having a downturned standard,l a heel plate securedthereon and having an `upturned nose piece, a bolt extendingtransversely throngh the nose piece, angle braces connecting said boltwith the standard, a plow foot comprising two spaced slotted barsengaging the bolt, one of said -bars being positioned on the boltintermediate the nose piece and each angle brace with the slots sldablyengaging the bolt, a rack plate secured on the plow beam, a V-shapedlever fulcrumed on the rack plate and having a short arm connectedpvotally with the upper endof the plow foot adjacent to one sidethereof, a brace connecting the relatively long arm of the lever withthe upper end of the plow foot,said brace being Pos1- tioned adjacent tothe side of the footy opposite to that engaged by the short arm of thelever, and means for retaining thelever ,9nd related parts at variousadjustments.

In testimony whereof I affix my signature in presence of two witnesses.
